Description

[Detailed Description of the Invention] "Prior Art" Conventionally, a fitting work was performed to attach a cross member 11 made of U-shaped steel to a steel upright column. Therefore, when dismantling a temporary structure made of a shaped steel frame for a work vehicle entry platform constructed at a civil engineering construction site, it is necessary to disconnect the contact area with gas, which not only damages the material and makes it difficult to reuse it. There were defects that made it difficult to improve construction and demolition work efficiency. In order to solve this problem, as shown in FIG.
A screw rod 7 is screwed into the female screw 4a provided at the tip of the horizontal plate 2 toward the outer surface, and the vertical groove 1
Insert the steel vertical edge 9a and tighten and fix it with the screw rod 5.
An assembly fitting was devised in which a horizontal member 11 made of U-shaped steel placed on the horizontal plate 2 is fastened and fixed to the above-mentioned outer surface with a screw rod 7 (Japanese Utility Model Publication No. 136006/1983).

However, in this assembly fitting, the lower part of the back of the web of the U-shaped steel horizontal member 11 on the horizontal plate 2 is tightened to the above-mentioned outer surface with the screw bolt 7, and the tip of the lower flange (edge 11a) is pressed against the above-mentioned outer surface. Not too much. Therefore, when the cross member 11 receives a force that tilts the longitudinal edge 9a of the steel material in the direction of the arrow b, the edge 11a slides upward along the outer surface, reducing the tightening force exerted by the threaded rod 7. 11 was at risk of coming off from the assembly fittings and the vertical steel edge 9a.

``Problem to be solved by the invention'' The present invention is to strongly support a horizontal member made of a U-shaped steel on an H-shaped steel member erected in a vertical direction by the above-mentioned assembly fittings, and the horizontal member is connected to the erected steel member and the assembly fittings. The purpose of the present invention is to obtain assembly fittings for temporary structures that are free from the risk of tilting or rolling outward.

``Means for Solving the Problems'' In order to achieve the above purpose, the present invention includes a horizontal plate 2 protruding from the outside of a groove-shaped metal fitting 3 in which a vertical groove 1 into which the vertical edge of the steel material can be inserted is formed, in a direction perpendicular to the groove 1. ,
A female screw 4 is provided from the outside of the metal fitting 3 toward the internal space of the vertical groove 1, a tightening screw 5 is screwed into the female screw 4 from the outside, and a screw thread 5 is screwed into the female screw 4 from the outside, and a female screw 4 is provided in the horizontal plate 2 facing toward the outside of the metal fitting 3. A female screw 4a is provided, a cross member insertion space a is interposed between the female screw 4a and the outer surface of the metal fitting 3, and a tightening screw 7 is screwed from the outside of the female screw 4a toward the outer surface of the metal fitting 3. Insert the ∧ into the tips of the screw rods 5 and 7 above.
In a temporary structure assembly fitting provided with a shaped blade 6, a protrusion 8 corresponding to the tip of the tightening screw 7 facing the outer surface is provided on the outer surface, and a protrusion 8 is provided between the protrusion 8 and the horizontal plate 2. Edge 1 of cross member 11 made of U-shaped steel
It is constituted by an assembly fitting of a temporary structure formed with an engaging groove 8b into which the fitting 1a is inserted.

"Function" Therefore, the vertical edge 9 of the H-beam steel 9 installed vertically
A is inserted into the vertical groove 1, and the vertical edge 9a contacts the bottom surface of the vertical groove 1. In this state, when the screw rods 5, 5 are rotated and propelled toward the vertical edge 9a in the vertical groove 1, the tip ∧-shaped blade 6 bites into the vertical edge 9a and is pressed against the tip surface of the screw rod 5. The metal fitting 3 can be fixed to the H-shaped steel member 9 by tightening the vertical edge 9a. Then, a horizontal member 11 made of U-shaped steel is placed or brought into contact with the space a of the horizontal plate 2, and the edge 11a of the horizontal member is inserted into the engagement groove 8b between the horizontal plate 2 and the protrusion 8. and lock the same end edge 11a with the same protrusion 8. In this state, as shown in FIGS. 3 and 10, when the tightening screw 7 is rotated and propelled toward the outer surface of the metal fitting 3, the tip ∧-shaped blade 6 bites into the cross member 11 and the screw rod The end edge 11a of the cross member 11 is engaged with and press-fitted to the projection 8 by the tip end surface of the cross member 11, so that the cross member 11 can be fixed to the H-shaped steel member 9.

"Example" An H-shaped steel member 9 is erected, and a horizontal plate 2 that is perpendicular to the groove 1 is protruded from the outside of a groove-shaped metal fitting 3 having a vertical groove 1 into which the vertical edge 9a is inserted. A female screw 4 is provided extending from the outside of the vertical groove 1 into the internal space of the vertical groove 1 to form the main body. A tightening screw 5 is screwed into the female screw 4 from the outside, and a female screw 4a facing the outer surface of the metal fitting 3 is provided on the horizontal plate 2, and the female screw 4a and the outer surface of the metal fitting 3 are connected to each other. A tightening screw 7 is inserted from the outside of the female screw 4a toward the outer surface of the metal fitting 3 with a horizontal member insertion space a interposed therebetween, and the protrusion 8 corresponding to the tightening screw 7 is inserted into the side of the female screw 4a. An engagement groove 8b is provided on the outer surface of the metal fitting 3 at a distance from the plate 2, and is formed between the protrusion 8 and the horizontal plate 2 into which the edge 11a of the horizontal member 11 made of U-shaped steel is inserted. And the screw rods 5 and 7 above
A ∧-shaped blade 6 is provided at the tip of the blade. The vertical groove 1 is formed so as to insert the vertical edge 9a of the H-shaped steel member 9 standing vertically, and the female screws 4, 4 are provided in a direction perpendicular to the direction of the vertical groove 1, as shown in FIG. As shown in FIGS. 9 and 10, it can be provided only on one side of the vertical groove 1. Space a is the vertical groove 1
on the back side (Fig. 2) or on one side (Fig. 8, 9).
(Fig.) and can be used depending on the direction of the H-shaped steel material 9. In the figure, numeral 10 indicates a connection plate between the metal fitting 3, the horizontal plate 2, and the female screw 4 or 4a, and 8a indicates a cross member receiving blade formed on the projection 8.

"Effect of the invention" Since the present invention is constructed as described above, it is possible not only to attach the cross member 11 to the vertical edge 9a of the vertical column made of steel material 9 very safely, quickly and easily, but also to install the cross member 11
The end edge 11a of the cross member 11 can be engaged and pressed to the protrusion 8, and there is no risk that the cross member 11 will tilt or roll outward, thereby preventing accidental detachment. Moreover, it can be quickly and easily separated and dismantled, and can be reused without damaging the steel members 9 and cross members 11.
